农作物遥感监测业务管理系统设计与实现

随着农作物遥感业务的不断延伸和农业生产管理对遥感监测需求的不断提高,业务运行管理效率问题日益凸显。该文通过对农作物遥感监测业务管理流程进行了系统化梳理与调整,设计开发了"农作物遥感业务管理系统"。该系统利用地理信息系统(geographic information system,GIS)、数据库技术和网络技术,科学设计了数据库系统,提升了业务系统承载能力;实现农作物遥感业务工作影像数据入库管理、查询、任务分发、上报、审核、归档的完整业务流程;建立业务跟踪管理机制,实现作物监测业务的流程化和可视化,有效提高了运行管理效率。

Design and implementation of business management system for crop remote sensing monitoring

Abstract: With continuous extension of crop remote sensing business and the needs for improvement of agricultural production and management of remote sensing monitoring, business operation and management efficiency has increasingly become a prominent issue. Based on systematic analysis and adjustment of the crop remote sensing monitoring business management process, the Crop Remote Sensing Business Management System (CRSBMS) was designed and implemented. By using Geographic Information System (GIS), database and network technology, the scientific database system was designed to improve the service system capacity and the complete business process of crop remote sensing was implemented, including image data storage management, query, task distribution, reporting, audit and archiving. The business tracking management mechanism was established to make crop monitoring business process standardization and to improve the operation and management efficiency.Based on systematic analysis, CRSBMS was designed as a four-part, image library management system: data transmission system, business tracking system and a one-stop portal. Image library management system is for managing the business involved in the procurement and archiving massive remote sensing image data. Data transmission system is for image data sharing and distribution between business organizational unit and business commitment unit. Business tracking system is designed for providing a visual business process tracking process, with real-time project progress intuitive presented. One-stop portal provide users with intuitive project overall briefing, describing the name of the project and their respective business units, the task is completed the case, the image data downloads.CRSBMS was designed using the hybrid structure of the C/S and B/S, in order to meet the system integration, stability, security, and ease of maintenance needs. Database development used Oracle 11g as a unified database platform. Client applications access the database through ArcSDE, server-side support for multi-user access.Version1.0 of CRSBMS was released in January 2011. We carried out a preliminary application in Agriculture crop monitoring business of Remote Sensing Applications Center of the Ministry. Results showed that CRSBMS basically has achieved the expected design goals:1) Completed crop monitoring business workflow and business-critical node, real-time, fully reflected the progress of the business, simplify data sharing processes, and improved the business management efficiency.2) The Database of CRSBMS, designed scientifically, could manage massive spatial data effectively, reduce the system response time of concurrent requests in significantly and enhance carrying capacity of business system capacity.3) Based on existing business processes, the system is lacking in flexibility. CRSBMS could be more flexible process customization based on business needs change in future, users could choose appropriate business processes and management models depending on different needs.4) To improve system security, further research is needed in the system encryption algorithms, hardware encryption devices and remote disaster recovery.
